MAX532ACWE集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

General Description

The MAX532 is a complete, dual, serial-input, 12-bit multiplying digital-to-analog converter (MDAC) with out put amplifiers. No external user trims are required to achieve full specified performance. The MAX532’s 3-wire serial interface minimizes the number of package pins, so it uses less board space than parallel-interface parts. The interface is SPI™, QSPI™ and Microwire™ compatible. A serial output, DOUT, allows cascading of two or more MAX532s and read-back of the data written to the device.

The device’s serial interface minimizes digital-noise feedthrough from its logic pins to its analog outputs. Serial interfacing also simplifies opto-coupler-isolated or transformer-isolated applications.

The MAX532 is specified with ±12V to ±15V power supplies. All logic inputs are TTL and CMOS compatible. It comes in space-saving 16-pin DIP and wide SO packages.
